Document Type and Number:
WIPO Patent Application WO/2018/030641
Kind Code:
A1
Abstract:
The present invention relates to a double heat insulation sleeve for passing a plastic pipe and a wire through a steel plate, the sleeve having a structure that enables the sleeve to be installed without a need to construct a separate heat insulation material in a steel partition wall or a steel deck in an area exposed to fire. According to the present invention, there is no need to construct a separate heat insulation material that is conventionally installed in a steel partition wall or a steel deck in an area exposed to fire, and thus the material and labor costs required for the insulation construction can be reduced. In addition, the present invention facilitates installation/construction in a steel partition wall or a steel deck in an area exposed to fire, and thus can minimize the number of construction workers and the time required for construction and can effectively prevent the spread of fire in a fire compartment without the conventional insulation construction.
